Built from submicron-grade solid carbide and coated with AlTiN+, this tool handles demanding materials while maintaining edge integrity at extended reach. The cutting diameter is 0.065 inches, the length of cut is 0.15 inches, and the overall length is 2.5 inches, making it suited for long-reach internal thread applications. With a right-hand flute direction and 3 flutes at 56 teeth per inch, it delivers clean thread form in blind and through holes alike. Machinists and CNC operators in precision manufacturing environments are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is used for generating 2-56 UNC internal threads on CNC machining centers where helical interpolation is available. Its long-reach geometry makes it appropriate for applications where thread depth or surrounding features restrict access to shorter tooling. The 1\/4 inch shank diameter is compatible with standard end mill holders and collet chucks. Typical applications include precision instrument components, electronics hardware, and small mechanical assemblies requiring fine unified threads.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron-grade solid carbide construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN+ coating provides high heat resistance and wear protection at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eLong-reach thread mill type accommodates restricted-access bore environments\u003c\/li\u003e\n  \u003cli\u003e3-flute helical design enables efficient chip evacuation during internal thread milling\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute direction compatible with standard CNC climb-milling strategies\u003c\/li\u003e\n  \u003cli\u003eSingle tool cuts the full thread profile via helical interpolation, reducing tooling changeovers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style thread milling solution for CNC machining centers capable of helical interpolation, sized for 2-56 UNC internal thread applications with a 1\/4 inch shank collet or end mill holder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed and operated by machinists or CNC programmers on 3-axis or greater machining centers with helical interpolation capability. Ensure the spindle and holder are fully secured and runout is minimized before operation, as carbide thread mills are sensitive to misalignment. Program helical interpolation to match the 2-56 UNC thread pitch; do not use this tool in a straight plunge or tapping cycle. Confirm that coolant-through is not required, as this tool does not support through-coolant delivery.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-56\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 56 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.065 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Mill Type\u003c\/strong\u003e: Long Reach\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN+\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SCIENTIFIC CUTTING TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TMLR065-56A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51971182231858,"sku":"TMLR065-56A","price":141.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b4daa2c6758cd334c71b72694412ff33.jpg?v=1789954295","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tmlr065-56a-thread-mill-2-56","provider":"Voomi Supply","version":"1.0","type":"link"}
